Gemini 2.5 Pro vs Gemini 2.5: What Are the Improvements? 204

Gemini 2.5 Pro is Google's latest released ai model. Compared to Gemini 2.5, Gemini 2.5 Pro outperforms Gemini 2.5 in reasoning, coding, multimodal support, and context handling, making it Google's most intelligent AI model to date.

Reasoning Capabilities

• Gemini 2.5 Pro: Its reasoning capabilities have been significantly improved, scoring 18.8% on zero-tool reasoning tasks, which is three times that of GPT-4.5 (6.4%). It also achieved an accuracy of 18.8% on the "Humanity's Last Exam."

• Gemini 2.5: Although it also possesses reasoning capabilities, its performance on complex reasoning tasks is inferior to that of 2.5 Pro.

Coding Capabilities

• Gemini 2.5 Pro: It performs exceptionally well in coding and can rapidly generate complex code. For example, it can generate a simple endless runner game within one minute. It achieved a high score of 63.8% on the SWE-Bench Verified test.

• Gemini 2.5: Its coding capabilities are weaker, and it cannot generate complex code applications as quickly as 2.5 Pro.

Multimodal Support

• Gemini 2.5 Pro: It supports multiple input forms such as text, audio, images, video, and code repositories. It performs exceptionally well in visual reasoning and image understanding, with a visual reasoning score of 81.7% and an image understanding score of 69.4%.

• Gemini 2.5: Although it also supports multimodal input, it is inferior to 2.5 Pro when handling complex multimodal tasks.

Context Window

• Gemini 2.5 Pro: It supports a context window of 1 million tokens, which will be expanded to 2 million tokens in the future. Its score in long-context evaluations far exceeds that of its competitors.

• Gemini 2.5: The context window is smaller, and its ability to handle long documents and complex conversations is inferior to that of 2.5 Pro.

Performance

• Gemini 2.5 Pro: It ranks at the top across multiple benchmark tests, such as exceptional performance on the GPQA and AIME 2025 tests. It holds the number one position on the LMArena leaderboard.

• Gemini 2.5: Its performance is inferior to that of 2.5 Pro, with weaker capabilities in complex task processing and multimodal understanding.
